March 13, 1962 Filed July 27, 1960 MN: NT WELDON J. ZDEL United States Patent 3,024,563 STORM SASH Weldon J. Zoellner, 10955 Ridgecrest, St. Ann, M0. Filed July 27, 1960, Ser. No. 45,729 1 Claim. (Cl. 2055) The present invention relates generally to the storm.

sash art, and more particularly to a novel storm sash which provides adequate 'air space between the pane thereof and the window sash with which it is associated.

Therefore, an object of the present invention is to provide a novel storm sash which incorporates depth between the panes thereof and the installation surface to insure adequate air space.

In brief, the present novel storm sash includes a mounting base extending continuously around and forming the sides of the sash, and a glass or pane receiving portion inwardly of and parallel with the mounting portion. The glass receiving portion is offset in respect to the mounting portion to provide substantial depth between the inner face of the glass and the outer or mounting face of the mounting portion.

Hence, another object of the present invention is to provide a novel storm sash in which the glass is offset from the mounting portion to provide substantial depth for an air space.

Another object is to provide a novel storm sash which is formed to provide a substantial air space and which is adapted to be mounted exteriorly or interiorly of the window frame.

Another object is to provide a novel storm sash incorporating a frame having a unique cross section providing a glass mounting ridge or shelf which is offset a substantial distance from the mounting surface of the sash, thereby establishing an air space of substantial depth.

Another object is to provide "a novel storm sash which is highly effective in performing its function of materially reducing the heat loss through the window with which the sash is associated.

Other objects are to provide a novel storm sash which is relatively inexpensive, which can be manufactured readily, which can be applied exteriorly or interiorly with ease, and which otherwise fulfills the objects and advantages sought therefor.

The foregoing and other objects and advantages are apparent from the following description taken with the accompanying drawing, in which:

FIGURE 1 is a front view of a storm sash incorporating the teachings of the present invention;

FIGURE 2 is an enlarged fragmentary front view of a corner of the storm sash of FIGURE 1;

FIGURE 3 is an enlarged fragmentary front view of one juncture of a cross strip in the storm sash of FIG- URE 1;

FIGURE is an enlarged horizontal cross-sectional view taken on substantially the line 4-4 of FIGURE 1;

FIGURE 5 is an enlarged vertical cross-sectional view taken on substantially the line 55 of FIGURE 1;

FIGURE 6 is an enlarged fragmentary front elevational view of one end of a cross strip employed with the present novel window sash; and

FIGURE 7 is an enlarged fragmentary rear elevational view of the same end of the cross strip of FIGURE 6.

Referring to the drawing more particularly by reference numerals, 10 indicates generally a storm sash constructed in accordance with the teachings of the present invention. The storm sash 10 includes a mounting portion 12 and an offset glass supporting portion 14 which are connected by a single web 15. A divider or cross strip 16 is provided for a large storm sash 10, such as that illustrated in the instant drawing. The storm sash 10 is illustrated as rectangular, a usual form, but it may take 3,024,503 Patented Mar". 13, 1962 any desired form required for the particular window with which it is to be associated. The frame of the storm sash 10 is made of extruded aluminum, as illustrated, but other materials and methods of forming may be employed.

The cross section of the mounting portion 12 is clearly illustrated in FIGURE 4. Adjacent channels 18 and 20 are provided. Channel '18 receives a sealing strip 22 of plastic or other suitable material. The channel 20 receives corner angles 24. The corner angle 24 may take any desired form and may retain the elements of the frame of the storm sash 14 in position by friction or by a press fit. For example, this may be done by indenting the aluminum frame of the sash near the corners at 26. A press die may then be used to force a small portion of the frame into the indentations. The frame may also be welded with or without the corner angles 24.

The cross section of the glass receiving or supporting portion 14 is obvious from FIGURE 4. An L-shaped member 25 consisting of legs 27 and 29 is supported perpendicularly and inwardly of the web by the first leg 27 while the second leg 29 supports the edge of glass panes 30. A continuous arcuate shelf member 28 is connected to the L-shaped member and supports glass panes 30 near the edge. The glass panes are maintained against removal by a sealing strip 32 which extends into a continuous channel 34 and is locked against removal in a key groove 36 provided in an arcuate channel member 37. It is clear that an air space of substantial depth is provided between the inner face of the glass 30 and the outer face 38 of the mounting portion 12.

The cross section of the cross strip 16 is clearly shown in FIGURE 5. The cross strip 16 includes opposed shelves 49 which receive the glass panels 30. Channels 42 are provided for receiving sealing strips 44.

It is manifest that the storm sash 10 may be suspended by suitable brackets secured to the upper edge thereof in the usual manner, or it may be disposed interiorly or exteriorly of a window frame and maintained in position by the usual pivoted clamps, or the like. In either case, a substantial air space is provided between the glass panels 30 and the glass of the window sash. A highly effective storm sash results.

It is apparent that there has been provided a novel storm sash which fulfills the objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawing have been given by way of illustration and example. It is also to be understood that changes in form of the elements, rearrangement of parts, and substitution of equivalent elements, which will be obvious to those skilled in the art, are contemplated a within the scope of the present invention which is limited only by the claim which follows.

What is claimed is:

In combination, a storm sash comprising a frame of integral cross section including a window frame engaging section, a pane supporting section, a single web connecting said two sections, and a pane carried by said latter section disposed perpendicularly to and spaced from said Web, said window frame engaging section being connected perpendicularly to the outside of the Web and including a channel receiving a sealing strip for engagement with an adjacent surface, said pane supporting section being offset by said single web from said window frame engaging section and extending inwardly of the web and including an L-shaped edge member having a first leg connected perpendicularly to the web and extending inwardly thereof and a second leg extending parallel with the web from an end of said first leg opposed to the web and serving as a seat for the pane, said pane supporting section further including an arcuate continuous shelf member connected to the second leg of the L-shaped edge member and engaging said pane along one side near the edge thereof, said panel supporting section also ineluding an arcuate channel member connected perpendicularly to the inside of the web provided with a groove receiving a sealing and retaining strip engaging said pane.
